During September and October, as Eonia dipped in and out of negative territory, there was a marked difference of tone when talking to US and European banks about whether a poster of euro cash collateral would have to pay rather than receive interest.
As a rule, the US banks assumed lofty, statesmanlike airs, calling on the industry to recognise the importance of the principle at stake – that negative rates are negative rates, and if clearing houses expect a collateral poster to pay interest in those circumstances, so should everyone else.
The European banks were more like school kids who had just managed to stub out and dispose of their cigarettes before the principal walked around the corner. There was a fair amount of smirking and a studied innocence. They were often quite interested in the legal niceties.
It was easy to imagine the conversations between US collateral receivers and European posters during those weeks.
US bank: "We have €3 billion of your collateral. You'll have noticed Eonia is negative. We assume you'll be paying up."

European bank: "Well, ordinarily, we'd be delighted, but I've just spent two hours talking to our lawyers and they say it's not clear there's an obligation to do so. We're trying to get a definitive answer, of course, but for now we've been instructed not to pay. Yes, yes, I know – I'm as frustrated as you."
Something like that, anyhow.
The divide can be seen in the list of signatories to the negative rates protocol, published by the International Swaps and Derivatives Association in May, which clarifies there is no floor on the interest payable – Bank of America Merrill Lynch, Goldman Sachs, JP Morgan and Morgan Stanley are all on board, but no big European dealers have so far joined them. As of October 29, Danske Bank and ING were the only major European banks to have signed.
Despite all of this, the size of the payments that would be required are small, perhaps running into the hundreds of thousands of euros and possibly touching the millions if Eonia remains negative for any length of time.
When pressed, traders on both sides of the Atlantic hold the same view: if the reference rate is negative, a collateral poster should pay. But lawyers insist the contract does not make that clear, so in the near term it should come as no surprise to see some banks using that defence.
In the longer term, the industry may well get its act together and sign the protocol en masse. But if that happens, I wager it will not be until Eonia is firmly back in positive territory.
